???? Welcome to CITEM. Remember to subscribe and activate the bell???? Within the world of urinalysis, the study of crystals in urinary sediment (crystalluria) plays an important role in being able to evaluate and correlate the metabolism of an individual. In summary, they give us an overview of the functioning of different metabolites such as calcium, urea, uric acid, cystine, this only with a general urine test performed in a clinical laboratory. There is a wide range of crystals that can appear in the analysis of a urinary sediment, and they can occur physiologically as well as in situations of illness, or also be secondary to the use of medications or bacterial processes. In this class, the different crystals present in the urine of a human will be reviewed (first of two classes), although these can also be observed in other animals, but it varies between each one and must be studied separately.
